Middletown police arrested a man accused of running a marijuana and hallucinogenic mushroom factory yesterday and said they found an arsenal of weapons and ammo in his apartment, as well as a stash of diamonds.

Vincent Sullivan, 24, of 498 High Street in Middletown, was arrested on Friday after police raided his house and car and prosecutors said he is a "large-scale drug dealer."

Police said Sullivan had security cameras covering the entrances to the apartment to monitor for thieves as well as police.

Inside the apartment, police seized 40 items from Sullivan, including a loaded AR15 assault rifle, which is a banned assault weapon; a loaded Mossberg 590 12 gauge shotgun; 11 30-round high .223 caliber rifle magazines, each loaded with 30 rounds; several boxes of ammunition of varying caliber; 1.6 lbs. of marijuana; a loaded Smith and Wesson .40 cal.; a Taser M26; suspected diamonds in a prescription bottle; a SOG machete; a knife with interchangeable blades; and several laptops and cell phones, police said.

One of the guns was stolen from Cromwell and Sullivan told police that a man who owed him money gave it to him two months ago, police said.

Sullivan also told police he bought the assault rifle during a private sale in Brooklyn, Connecticut and that he buys marijuana for around $3,000 and sells it for $3,300, according to the arraignment report.

Police determined the street value of the drugs found was $15,060 for the marijuana and $200 for the mushrooms.

One of the laptops, a Macbook computer worth $1,100, was reported stolen from a Wesleyan University student in April 2012, police said.

The arraignment report also said Sullivan had a heat-sealed bag of hallucinogenic mushrooms, digital scales and a diamond analyzer.

Department of Labor records state that Sullivan made just a few thousands of dollars each year since 2010, but police found $14,180 in cash in the apartment, which was furnished with expensive electronic equipment and furniture.

Several drugs and weapons charges were filed against Sullivan, including operating a drug factory near an elementary school, illegal possession of an assault weapon,

Sullivan lives in the apartment with his fiancé and infant daughter, who were not home when police served the search warrant was served. He was also charged with risk of injury to a minor, fourth-degree larceny and motor vehicle violations.
